PermaFlex®, and all its grades, is a thermoplastic elastomer, based on copolyester chemistry, also known as COPE or TPE-E. It eliminates the demarcation between rubbers and engineering plastics. It combines the strength and processing characteristics of engineering plastics with the performance of thermoset elastomers, a combination of the most desirable characteristics of rubbers and plastics. This combination provides benefits in processing and productivity for both molders and extruders. It also can be processed by blow molding or rotational techniques. As a thermoplastic, PermaFlex does not involve the high cost of vulcanization to obtain optimal properties. This polyester-based material offers a consistent performance over its entire operating temperature range, since its properties vary minimally from high to low temperature extremes. PermaFlex polyester-ester technology extends the traditional temperature range of thermoplastic elastomers.
